NOZZLE FOR STREET-SPRINKLERS.

SPECIFICATION forming part of Letters Patent No. 464,550, dated December8, 1891. Application filed May 29, 1891. Serial No. 394,570. (No model.)

To aZZ whom it may concern.-

Be it known that I, FREDERICK E. BOWMAN, acitizen of the UnitedStates,residin g at South Bend, in the county of St. Joseph'and State ofIndiana, have invented certain new and useful Improvements in Nozzlesfor Street- Sprinklers; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to nozzles designed particularly for use onstreet-sprinklers, though applicable to any use where sprays of waterare designed to be projected and where it is desirable that the quantityof the Water discharged be under immediate control through an easily andrapidly operated device.

The object of the invention is to produce a nozzle of the simplestpossible construction, composed of few parts, easily made, and capableof being rapidly assembled, whereby by a very simple manipulation of amoving part the quantity of water discharged may beregulated.

Furthermore, the object of the inventionis to produce a nozzle designedparticularly for use on street sprinklers, which shall be of suchconstruction as to require no valve of the ordinary construction forregulating the admission of water to the nozzle and in which the partsshall be so constructed and arranged that they will act as a valve toregister the flow of water, thereby obviating the use of a constructionwhereby stopping of the Waterpassage or inlet-pipe by stones, dirt, orthe like is obviated.

Furthermore, the object of the invention is to produce a nozzle designedparticularly for use on streetsprinklers in which a minimum number ofparts are employed and which is so constructed that the parts mayreadily be separated for the purpose of allowing access to the interiorof the nozzle to remove any foreign substances which might tend toobstruct the passage of water.

Furthermore, the object of the invention is to produce a nozzle designedparticularly for use on street-sprinklers in which the discharge of thewater from the'nozzle shall be so directed as to render the dischargefrom all parts of the nozzle uniform, thus obviating the discharge ofany greater quantity of water at one point than at another, resulting inwashing of the street being sprinkled.

The invention consists in a sprinkler-nozzle composed of a pipeconnected with a source of Watersupply, a smaller pipe having one endclosed and provided on its circumference with discharge openings orperforations, the smaller pipe being also provided on its interior witha deflecting-plate, whereby water is deflected from the lowerdischarge-openings, thereby preventing an abnormal discharge at thatpoint and preventing washing of the street.

The invention is illustrated in the accompanying drawings, in which- IFigure 1 is a side elevation of a sprinklernozzle constructed inaccordance with my invention. Fig. 2 is a central longitudinal section.

In the drawings, A represents a cylinder, which in use is preferablyhorizontal, and is supported and attached to a sprinkler-wagon or anyother body in connection with which it is to be used by suitablesupports a. Attached to one end of this cylinder A is a pipe Bcommunicating with a source of water-supply and connected with thecylinder A by a tight-joint B, provided with suitable packing b,insuring a close fit.

0 represents a smaller cylinder designed to enter and slide freely backvand forth in the cylinder A. The cylinder 0 has its outer end 0 closed,and its periphery is provided with a series of openings 0', preferablyextending around the bottom and a short distance up the sides of thecylinder. Attached to the outer end 0 of the cylinder 0 is a projectingarm 0 to which is attached a lever 0 connected with any suitableoperating lever or red, by which a sliding motion may be communicated tothe cylinder 0, and the same moved back and forth in the cylinder A toexpose a greater or less number of openings 0', and thereby regulate thequantity of water discharged.

Interposed between the cylinders A and C are packing-rings 0 whereby awater-tight joint between the two cylinders is obtained.

Located within the oylinderC isadefieotor,

fender, or partition D, extending across the cylinder 0 about the centerthereof and having its inner end (1 extending downward to within a shortdistance from the bottom of the cylinder. The purpose of this deflectoris to direct the water passing into the cylinder B from the bottom ofthe cylinder, thereby preventing discharge of the water at that point intoo large quantities, which might result in washing the street uponwhich the sprinkler is used. A sufficient space is left between theportion d of'the deflector and the bottom of the cylinder 0 to permitthe passage of the water in a suiiicient quantity to the lower portionof the cylinder 0 to cause a discharge of an equal quantity from thatportion to that discharged from the other portions of the cylinder.

While I have particularly described the perforated pipe as beingarranged in the interior of the other pipe, it will be understood watermay readily be regulated and in which no valve which is liable to becomeclogged is used. It will also be seen that my construction renders theseparation of the parts easy, thus facilitating cleaning of the interiorof the nozzle.

Having thus fully described my invention, what I claim as new, anddesire to secure by LettersPatent, is

A sprinkler-nozzle composed of an unperforated pipe connected with asource of watersupply and a perforated pipe having its outer end closedand provided on its circumference with discharge-perforations, theperforated pipe being placed in connection with and sliding back andforth with relation to the other to expose a greater or less number ofdischargeopenings, the perforated pipe being provided with adeflecting-partition provided with a depending end, whereby water isdirected from the bottom of this pipe, substantially as described.

I11 testimony whereof I affix my signatu re in presence of twoWitnesses;

FREDERICK E. BOWMAN.
